Children were asked to quantify how much time they spent gaming on a typical school day - using consoles or computers.

They then rated a number of factors, including:

Satisfaction with their lives

How well they got on with peers

How likely they were to help people in difficulty

Levels of hyperactivity and inattention

The answers were combined to assess levels of psychological and social adjustment.

When compared with all other groups, including those who played no video games at all, young people reporting under an hour of play each day were most likely to say they were satisfied with their lives and showed the highest levels of positive social interactions.

The group also had fewer problems with emotional issues and lower levels of hyperactivity.

According to the results, people who spent more than three hours playing games were the least well adjusted.

'DIGITAL WORLD'

Dr Przybylski says there may be numerous reasons behind this.

He told the BBC: "In a research environment that is often polarised between those who believe games have an extremely beneficial role and those who link them to violent acts, this research could provide a new, more nuanced standpoint.

"Being engaged in video games may give children a common language.

"And for someone who is not part of this conversation, this might end up cutting the young person off."

He argues that policies and guidelines that impose limits on the use of this technology need to take such evidence into account.

Dr Przybylski points out that though the effect of video games on children is statistically significant in this study, factors such as the strength of family relationships play a larger role.

Dr Iroise Dumontheil, of Birkbeck, University of London, who was not involved in the research, said: "Other studies have shown that playing first-person shooter games, but not other types, can lead to increased visuospatial processing and memory abilities.

"Further research would help to determine whether particular types of game help or hinder adolescents as they adjust to the changes they experience during development."
